PLEASE HELP ASAP I NEED ANSWERS FOR ALL 3 For numbers 7-9, let:
f(x) = 4x + 2
g(x) = x^2 - 1

7. Find (f. g)(x)
8. Find (gºf)(x)
9. Find (f o g)(3)

To get the original price we are going to;

1) Subtract the discount percentage from 100 to get the original price percentage.

100 - 25 = 75 %

2) Now we are going to multiply the discounted price by 100.

7500 x 100 = 750,000

3) Now we are going to divide the discounted price by the original price percentage.

750,000 / 75 = 10,000

Therefore the original price is Rs 10,000
